Error com.thinkaurelius.titan.diskstorage.keycolumnvalue.keyvalue.OrderedKeyValueStoreManagerAdapter is not supported

I am using Titan 1.0  with Berkeley DB and Elastic search engine for indexing with conf/titan-berkeleyje-es.properties file.
I am trying to index test-database using the test example as mentioned in the link :
http://s3.thinkaurelius.com/docs/titan/1.0.0/index-admin.html

I am executing the steps as mentioned in  "Reindex Example on MapReduce"

I get the following error while executing the test example for "updateIndex"

gremlin> graph = TitanFactory.open("conf.properties")
==>standardtitangraph[berkeleyje:/home/ambertag/db/berkeley]
gremlin> g = graph.traversal()

Store manager class class com.thinkaurelius.titan.diskstorage.keycolumnvalue.keyvalue.OrderedKeyValueStoreManagerAdapteris not supported

I have a running instance of elasticsearch .
Is there anything that i am missing ? Any changes to be made to  updateIndex?

In order to use the MapReduce job to reindex, you'll need to use a distributed backend -- HBase or Cassandra. For Berkeley, you should reindex via TitanManagement.

http://s3.thinkaurelius.com/docs/titan/1.0.0/index-admin.html#_preparing_to_reindex

"Reindex on MapReduce supports large, horizontally-distributed databases. Reindex on TitanManagement spawns a single-machine OLAP job. This is intended for convenience and speed on those databases small enough to be handled by one machine."

Thanks Jason.
I am not getting any errors now for updateIndex.

Is there a way to check whether my indexes are set ?
This is the execution statement after I set the index as mentioned in the example."Example for TitanManagement". Note that there is no planner WARNing statement.
gremlin> g.V().has("name", "lop")
gremlin>


However, if I execute:
gremlin> g.V()
11:49:22 WARN  com.thinkaurelius.titan.graphdb.transaction.StandardTitanTx  - Query requires iterating over all vertices [()]. For better performance, use indexes
==>v[4096]
==>v[4168]
==>v[4192]
==>v[4200]
==>v[8296]
==>v[4224]


Are my indexes set ? How do i check them out?
